Perennial pepperweed is a perennial that can grow from 1-5 ft. (0.3-1.5 m) in height. In the late fall to early spring a rosette of leaves develops with 4-12 in. (10-30 cm) long and 1-2 in. (2.5-5 cm) wide, toothed leaves. Rosette leaves are long petiolate. Cauline (stem) leaves are alternate, 1-3 in. (2.5-7.6 cm) long and oblong. Flowering occurs in the late spring to summer, when flat, dense clusters of flowers develop at the apex of the flowering stem. Individual flowers are 4-petaled and white, each producing a round to oval, hairy pod that is 1/16 in. (1.5 mm) in diameter. Perennial pepperweed is native to Eurasia and occurs in coastal wetlands, riverbanks, marshes, rangelands and roadsides. It was accidentally introduced into the United States around 1936 as containment in seed.
